RAILROAD WATER-TAN K..

SPECIFICATION forming part of Letters Patent-No. 392,371, dated November6, 1888.

Application filed June 25, 1868. Serial No. 278,18 (No model.)

To a2; whom it may concern:

Be it known that we, JOHN SKINNER and ROLLY IV. JACKSON, of Newman, inthe county of Douglas and State-of Illinois, have invented a new anduseful Improvement in Railroad Water-Tanks,of which the following is aspecification.

This invention relates particularly to the arrangement of the valve tothe valve-stem,

the connecting-rod inclosed in a tube and attached to the'lever beneaththe valve-seat at one end and to the valve-seat at the other end, alsoto the steam or hot-air pipe connected with the valveseat, and to themethod of operating the various parts.

The objects of the improvements are to prevent the valve and itsconnections and the outlet-pipe from becoming inoperative from thefreezing of the water in the tank, and to do this effectually andcheaply.

The figure is a vertical section of a watertank provided .with ourimprovements.

In the accompanying drawing, X X is the valve-seat of our improvement inrailway water-tanks,which is formed in the top of a closed chamber orcase constructed in the bottomof the water-tank.

A is the valve,through which the valve-stem B passes and to which it isfixed. This stem is supported in a vertical position by the loophrace Oat the upper end, and is bolted to the lever D at G. The lever D ishinged to the valve-seat X at P, and also to the connectingrod F at E.The connectingrod- F is also hinged to the lever L at I. The upper endof the connecting'rod F has a valve, H, in the tube G,which latterextends down to and opens under valve-seat X.

L is a lever hinged at K to operate both the valves H and A.

N is a pipe for introducing steam or hot air under the valve A to thawout any ice that may form in the outlet-pipe M.

The connecting-rod F is incased in the tube G to prevent its beingfrozen in ice, which would make it immovable.

A depression of the upper end of the lever L raises the valve H and theconnecting-rod F, also the lever D and valve A, permitting the water inthe tank to pass under the valve under the ice. Our improvement obviatesthis diffioulty by admitting air through the tube G under the ice to thebottom of the tank on raising the valve H. The valve H also prevents,when closed, a circulation of air through the tube G and the outlet-pipeM, which circulation of air would have a tendency in cold weather tofreeze the water in the outlet-pipe. The valve A being above thebottomof the tank, sediment will remain on the floor thereof and notpass out through the valve into the outlet-pipe, thus serving in ameasure as a purifier.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent-- 1. The combination,with a water-tank, of aninclosed chamber or casein the bottom of the same having a valve openinginto the tank and an outlet-pipe leading therefrom for water, anair-tube, G, leading to the outer air from said chamber, a valve, H,fitting the outer end of said tube and having a rod, F, extendingthrough the air-tube to the closed chamber and connected to andoperating the valve. substantially as shown and described.

2. The combination,with a water-tank, of an air-tube to admit air underthe surface ice, a chamber or case arranged in the bottom of the tankand provided with an outlet pipe and valve, and operating mechanism forthe valve extending through the air-tube into the chamher to operate thevalve, substantially as and for the purpose described.

3. The combination,with a Water-tank having a closed chamber in itsbottom with an outlet-pipe therefrom, and a valve opening from saidchamber into the tank, ,of a steam- 5 pipe, N, extending from theoutside of the tank to the interior of the chamber in the bottom of thetank,substantiall y as shown and described. 4. The combination of awater-tank having a chamber in the bottom of the same provided with anoutlet water-pipe, a valve, A, opening upwardly into the tank from thesaid chamber, a lever, D, arranged within the said chamber and connectedto the valve, an air-pipe, G, extending from the top of the tank to thechamher in the bottom, and a rod, F, having a valve, Ill, at its upperend and extending through pipe G, and connected to and operating uponthe lever of the valve within the said chamber, substantially as shownand described.
